Ado|stream First, MP3 's ID3 tag, because it's mainly about manipulating this thing.
MP3 at the very beginning without what we see today, there are singers, times, albums and so on.
Only a few simple parameters such as yes/no to express is not privated or copyrighted information, so that MP3 related to the work caused a lot of inconvenience, 1996 when a foreigner proposed to each of the MP3 appended a piece of data to store the above information, And then it developed into a ID3 v1. As far as I know, it's 1.1 now.
Or the old habit, with metadata to introduce the DLL, I used to have articles posted, do not know please check yourself
Look at the code
